Image pickup device for judging and displaying hand-waggling level and cellular phone using the same

An image pickup device comprising:

• an electronic image pickup portion for picking up an image of a subject and generating image data;
• an angular velocity detecting portion for detecting an angular velocity of the electronic image pickup portion;
• a rotational angle detecting portion for detecting a rotational angle of the image pickup device on the basis of the angular velocity detected by the angular velocity detecting portion;
• a hand-waggling level judging portion for judging a hand-waggling level of three or more stages on the basis of the rotational angle detected by the rotational angle detecting portion, wherein the hand-waggling level judging portion has a storage table representing the relationship between the rotational angle and an image damage sensitive level as the hand-waggling level, and wherein the hand-waggling level judging portion determines the image damage sensitive level on the basis of the rotational angle by referring to the storage table;
• and
• an image data managing portion for determining on the basis of the judgment result of the hand-waggling level judging portion whether the image data picked up by the image pickup portion should be saved or discarded;
• wherein the storage table includes a first range of image damage sensitive level threshold values and a second range of image damage sensitive levels, wherein the first range corresponds to lower rotational angles than the second range, and wherein the second range is larger than the first range, and
• wherein the storage table includes a first axis representing the rotational angle, a second axis representing the image damage sensitive level, and a substantially parabolic curve representing a relationship between the rotational angle and the image damage sensitive level.
